Imapsync

We are trying to use imapsync to move mail from thunderbird. We are experiencing mixed success. Some folders copy over great. Others error out right at the end stating - Couldn't append message # Then it finishes without syncing mail. Any ideas on this?

I am currently running imapsync and a tail on maillog and I don't see any errors showing up. Would you happen to know what the flag would be to set max messages. If this is the issue I would like to set it to unlimited.

IMAPsync - Attechment size

The max attachment size it the only time I had those errors with IMAPsync. Took a lil while to find it but MMORSE points you to the exact link with the answer. Our company previously had no attachment limit so some of the files were rather large.
